To all @Mom @may concern: v

1Be `it known-that we, EvAN B. IAIILLMAN, i

`foinia, have invented new and useul lim provenients in Concrete `Forms for Reen- `forced lollow` Walls, of whichtherifollowlltisthe object of this inventionto provide a form for making concrete walls eitherv assolid` walls`orhollowlwalls, the form also permitting` of .the placin of usual or any desired tie rods' and rein iorcing'` niembers-inthe wall construction. l e

Theimproved torni permits of the continuous pouring of a concrete `wall, the construction'being so arranged that after one *level ojf thewall has'beein poured and has set, that the form may be moved upwardly "upon this level Vofthe wall so as to permit pouring of the next upper level.

`from the :following` descriptionofftheace companying drawings, in which: y

Figurelis a side elevation ot a wall beform; l e y y Fig; 2 is a transverse sectiony on `2`-2`offl `igz 1, V, ,l

Figm is a detail section'on the lined-#s3 of Fig-J2. 1^ v f l v y Fig. l is aldetail section on theline eze-4t or tigri. l l M the line ,transeversely spaced walls forming a hollow i of the `inriprcved form are `shown at i-i and latter case but one ofthe wall forming molds `olI `the"apparatus being employed.

y the next` upper `level sleeves@ slidableathereon. Arms 3 project `The invention will be readily understood from opposite sides ofthese `sleeves so as to overlie the wallsA and B "in course of construction, and side plates 4L and 5 are suspended from each of the arms 3 in transversely spaced' relation so as to provide a 1 `rorm in whichthe concrete is poured in 0rder to form the walls. A

VThe side vplates are made in suitable lengths, and at the meeting endsoiz the sections :forming a sidewall, lap joints are provided by means of plates 6.' Suitable retaining means including hook members 7 `are provided for connecting adjacent sec- The side walls i are v tions of a sidewall. suspended from" arms 8 extending upwardly beyond the upper edges of the walls', and these arms arespaced along the side walls oppositethe respective standards l; w The garnis are mounted upon the1 laterally `projecting arms 3 and may be adjustably transversely spaced in order to provideforms of varyingE thickness, sothfat walls of different thickness may be poured between the side walls comprising a form. As an instance of thisarrangement a series of apertures 9 are provided along arms 3, and `arms 8 maybe f suspended from arms 3 `at desired `cries lof these apertures as by receiving suitablefasteningboltsl() througharins Sand said A depending from armsm8 `are `received against opposite sidesof a wall in `course of constructionVand `may be held against the same by means of a set screw ll threaded throughthe end. 12 of onel of the v l larms 8 beyond its pivot bolts 10, and are yln the present embodiment of the invention we have` shownthe improved "form as f ,i employed inf the construction of parallel ranged to impinge against the end 120i the Bother arm 8, so that the arms may be swung upon the pivots provided by bolts l0 through adjustment Vof the set: sere wall construction. *lt willbeapparent howl By this arrangement when 'sleeve -2' and the side walls of the `form `carried thereby have been elevated so that the lowerI ends of the sidewallsare received against opv 1l, `andthe sidewalls will then prov-idea` form for the next uppery level of' the wall. 1When this level has been poured,` andf has 'set`,the clampingengageinent ofvgthe "iside walls may be released by reverselv turning` set screw 1l, so that sleeve 2 and the. side f vlike as well as outer walls.

walls carried thereby may be again elevated upon standard 1 and thus provide for a continuous wall construction.

The means employed for thus elevating sleeve 2,'and subsequently holding the same With relation to standard` 1, includes a clamp ing bearing 14 received upon standard' 1 above sleeve 2, and having a laterally projecting arm 15. A'iie'xibleconnection 16 is secured to the lower end of sleeve 2 which :for this purpose is provided with lugs 1i", and-,at its upper end this flexible connection is secured toI the'end of arm 15. By thisr arrangement when the weight of the form is upon sleeve 2, arm 15 isswung downwardly through flexible connection 16, and as a result the bearing 14 binds upon standard 1 so as to prevent said bearing sliding downwardly upon the standard, and as a consequence sleeve 2 and the form carried .thereby held in position upon standard 1 by connectionv 1,6 and the arm 15.

' The means employed for subsequently elevating sleeve 2 upon the standards ncludesv clamping bearing 17 arranged upon standard 1 above bearing 14, and having a laterally lprojecting arm18 provided with -fafweight 19 so as to normally move the nclamping bearing into binding engagement upon standard 1. A lever 20 is pivoted to armr 18, and a link connection 21 is providedbetweenathis lever and a lug 22 projecting from the lower end of sleeve 2. The lever 20 is so. arranged that downward lmovement of the .operatingv handle thereof Will swing clamping bearing 17 against the Iaction of weight 19 so as to destroy the v binding engagementy of the bearing upon standard 1, and continued downward movement of the handle of the lever will slide the bearing upwardly upon the standard. Assoon as the lever handle-is released the weight 19 will again cause the bearing to bind uponthe standard, and lifting yof the [lever handle will then elevate sleeve 2 .through the link connection 21.

This operation is-repeated until the form has been raiseda sufiicient distance to permit of vpouringv of lthe next upper level of the wall `under construction. i

It will thus be seen that I have provided 4a form for vconcrete wallsby the use of which wallsy may be continuously poured. It will bev understood that the form may be so arranged as to construct either straight, curved, or angle walls, and may be employed in" the construction of partitions andi the It will also be apparent that any suitable tying or rein- .forcing means may be employed in connec- Jtion with the walls duringeonstruction of thesame.

lVarious changes may be made without departing from the spirit of the invention v:as claimed. l

otally connected to and suspended from said 7 cross arm, means associated with the upper ends of said form sections for clampingr their lower portions against an interposed wall, and means actuated by the weight of the slidable member and the parts carried thereby for clampingl the standard to retain the supported parts at the desired elevation which means includes a clamping member that engages the standard above the slidable member, an arm projecting outwardly from said clamping member, and a chain extending from the outer end of said arm downwardly to the lower end of said slidable member.

2. In a concrete form, a standard, a member slidable thereupon, a cross arm carried by said member, a pair of form sections pivotally connected to and suspended from said cross arm, means associated with the upper ends oi' said form sections for clamping' their lower portions against an interposed wall, means actuated by the weight of the slidable member and the parts carried thereby for clamping the standard to retain the supported parts at the desired elevation, which means includes a clamping member that engages the standard above the slidable member, an arm projecting out- Vwardly from said clamping member, and a chain extending from the outer end ot said arm downwardly to the lower end of' said slidable member, and means connected to the slidable member and to the standard whereby said slidable member and the parts carried thereby may be moved upwardly upon said standard.

3. In a concrete form, a standard, a meniber slidable thereon, means for movingT said slidable member uinvardly upon said standard, a clamping member positioned on the standard above the slidable member. an arm projecting outwardly from said clamping member, a chain secured to the outer end of said arm and to the lower end of said slidable member, a cross arm carried by said slidable member, a pair of vertically disposed bars pivotally and adjustably connected to said cross arm, form sections carried by the lower ends of said arms, and a screw rod passing through the upper portion of one of said bars and engaging the upper portion of the other, whereby the lower portions of the form sections may be moved toward each other to clamp an interposed wall.

In testimony whereof we have signed our names to this speciication.
